ARTHUR H. C. MEYER, OF FORT WAYNE, INDIANA.

. VARIABLE-FEED GEABING.

' Be it known that I, ARTHUR Q. MEYER, a citizen of the United States of America, and resident of Fort Wa ne, in the county of Allen and State of In iana, have invent-. ed certain new and useful Improvements in Variable-Feed Gearing, of which the following is a specification.

This invention relates to improvements in variable feed gearing, and the object thereof is to afford a simple construction by means of which a feeder maybe operated at vari-. ous speeds while the driving member ro-' tates at a constant velocity, or the ratio of rotation between the driving and driven 'members 'may be adjust'ably varied. This object is accom lished by the construction illustrated in tl te accompanyingdrawings, in which- Figure 1 is a longitudinal section showing the relative arrangement ofparts; and Fig. 2 is an end view of the driving-and driven members, the former partly cut away.

Similar numerals of reference mdicate corresponding parts in both views, and referring now to the same: 1 is a feed box having in its lower'part a shaft 2 that has in connection therewith a feeder 3 of .a' ty e ada ted to be actuated upon rotation of t e shaft. The feeder shown is a spiral conveyer of well known form, but in matter of type is immaterial to the present invention, any other feeder adapted to be operated by the rotation of the shaft being more or less serviceable.

The shaft 2 extends through the end of the feed box and has fixed thereon a star wheel or driven member 4 by which it is actuated. Another shaft 5 is mounted in parallel relation with the feeder shaft 2 and has thereon a driving member consisting of a revoluble pulley 6 with an adjustable disk 7 in concentric relation therewith, and which is provided with an annular series of pins 8 holes in t of various lengths. The pulley has at its side a radial flange .9, andan annular series of ho cs 10, corresponding with the pins, extend through the side of the pulley, and an other series of holes 10'iextend through the flange at points correspondingl oppositethe e pulley. Between t e flan e and pulley is an annular space 11 into which the star wheel extends part way. The pins 8 are adapted to be extended through the 'corre sponding holes so as to'engage. the teeth of Specification of Lcttcrs ratcnt. Patented Sept. 13, Application filed November 1, 1909.

the star wheel. and drive the same upon rotation of the driving member.

The disk 7 has a sleeve 12 with which an adjusting lever 13 has connection so that the disk can be shifted to extend one.or more of the pins through their corresponding openings and into working relation with the star wheel, or all of the pins may be drawn back by the movementof the disk so as to miss the star wheel entirely. When the pins'are in the latter position the star wheel is idle;- when one in only enga es the star wheel, the latter-1s moved one raction of a cycle -with each com lete cycle of the driving member; and w on more of the pins engage the star wheel, it is moved asmany more fractions of a cycle as there are ins engaging it with each com lete' cycle '0 the drivin member. It will t erefore be understoo that the ratio of movement between the driving and driven members will vary ac 'cordingly as the lever'13 is shifted, and the feeder will be'actuated accordingly.

I The pulley may be driven by any suitable means such asbya belt, and the adjusting lever may be supported in any convenient manner such as by a bracket 14. Having described my. invention, what I. claim as new' and desire to secure by Letters Patent is:

1. A mechanical movement comprising a revoluble driven member; a driving member; a disk in adjustable relation with the driving member, the latter having an annular series of holes in its end; an annular series of pins extending from the disk and adapted to'project through the corresponding holes in the driving member upon adjustmentof the disk, said pins being of different lengths; and means toshift the disk.

' 2. A mechanical movement comprising a revoluble driven member; a drivin member; an annular series of pins 1n ad ustable relation with the driving member, said pins being of difl'erent'lengtl'is and adapted to be projected throughthe end of the driving member" and into engagement with the driven member and actuate the same upon rotation of thedriving member; and/means 105 to adjust the pins.

3. A mechanical movement comprising a revoluble driving member; a star wheel; an annular-series of adjustable pins in connection with the driving member adapted to be shifted successively into engagement with the star wheel and actuate thesameupon rotation of the driving-member; and means to shift the pins.

4. In a mechanical movement, a drivin member comprising a pulley havin a radia flange adjacent thereto, the end of t e pulley having an annular series of holes therein and the flange having a like series of holes correspondingly opposite those in the-pulley; an annular serles ofadjustable pins in connection with the pulley adapted to be projected successively through the corresponding holes respectively; a star wheel c of the pulley and means to shi of extending between said pul ey and flange and being adapted to become engaged and actuated by the pins when the latter are projeoted through the holes and uponhrotetion t t e pins.

In testimony whereof I afiix my signa- 2o ture, in presence of two witnesses. o
